Nokia Purity and Purity HD target phones

Nokia World's focus included a branching out for more general-purpose audio through a team-up with Monster Cable. Both the Purity in-ears and Purity HD over-ears are intended to pair up with the Lumia Windows Phone line and gives them uncommon support for remote control and calls. The Purity HD headphones also bundle a second fully-capable remote for "other devices."

Both headphones have a 20Hz to 20kHz frequency range with a 32-ohm impedance; Nokia claims deeper sound from Monster. The in-ear Purity models have standard-sized 9mm drivers, and the Purity HD through its larger size gets 40mm drivers.

Nokia wasn't specific on ship dates or pricing for either set, although the Monster connection could see them appear in the US along with Nokia's preferred areas. Both the Purity and Purity HD will be available in black, cyan (blue), fuschia (pink), and white.
